To (ZZZ whom it may concern:

Be it known that, l,- Wnmrarr Samoa,

a citizen of the United $tates, residing at.

Belleville, in the. county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Impact-liegisters, of which the following is a specification. Y

This invention relates to impact registers and it consistsiin the novel features hereinafter described and claimed.

An object of the invention is "to provide a register of simple and durable structure adapted to be positioned upon a car or moving vehicle and which is adapted to indicate and show the force of impact which is extended or-exerted when the cars are brought together during the operation of coupling the same or at other times This device will record the rough handling of cars in transit and is of value to the railroad in determining where cars are handled roughly and also in the settlement of claims for broken freight in inter-road movement.

Heretofore themanagement of roads were at a loss to know where irei ht was handled roughly and by what conductors such handling was done, with the present invention they can tell the time of such rough handling, the weight or force of the impact and if necessary the name of the conductor in charge of the car when it received the rough handling. This is determined by the reg-ister on the chart which shows the time and indicates the-force of the impact in pounds.

With the above objects in view the register includes a casing adapted to be mounted uponthe wall of a car and which is provided with rollers having a chart wound upon the same. Any suitable means may be provided iorrotating the rollers and in fact the said rollers may be rotated simultane ously by a clock or other spring mechanism. Partitions are arranged in the casing and bars are movably mounted transversely through the partitions. The said bars are three in number: two of them being guide bars and the other being a bar which carries a needle adapted to move over the chart as j the said chart is wound upon one roller and unwound from the other. A weight is mounted upon the said bars and springs are attached at their inner ends to the weight and pass through the partition and are provided at their outer ends with stops which normally lie against the outer surface of the Eigecifioation of Letters 'Eatent.

partitions 2 are provided with alined openings 3, 4 and 5. Rollers .6 are journaled for rotation at the lower edges of the openings Bars 7, 8 and9 areslidably mounted in the open ngs 3, 4 and 5 respectively and a weight 10 is mounted upon the intermedia e portion of the bars 7., 8 and 9 between; the partitions 2.' The bars 9; rest upon the upper portions of the peripheries oi the rollers 6 and sustain the weight of the body 10 and the bars 7 and 8.. Coiled springs 1,1 arefixed at their inner ends t the opposite sides of the we1gl1t .19 and receive the opposite end portions of the bar 8. The outer; end por-. tions of the springs 11 pass through the partitions 2 and are provided wit-h caps or stops 12 which normally bear against the outer surfaces of the partitions 2. The bar 7 is merely a guide bar to hold the parts in proper relation with respect to each other.

The bar 9 sustains the weight of the parts hereinbefore indicated While the bar 8 carweight 1 0' is normally held approximately midway between the partitions 2.

Beyond. the outerside of one of the parti- 3 tions2 and within the'casing 1 are journaled rollers 14 and any suitable means may be provided forsimultaneously rotating the rollers 14 in the same direction. A chart 15 is wound upon the rollers 14 and may be provided with any suitable lines or graduations and the pencil 13 normally rests against the chart 15 at a point approXi-- thereof. I

In operation the rollers 14 are-caused to rotate simultaneously in the direction as above indicated whereby the chart 15 is unmatelv midway between the opposite edges wound from one roller and wound upon the other at a predetermined rate of speed. This rotating of the rollers may be in accord with a timing mechanism as for instance as a clock or any suitable means may be pro- I vided for'rotating the rollers; As the car or during the operation of coupling the same the shock incident to bringing the car to a sudden stop by' striking an object at rest causes the weight 10 to move from its normal position approximately midway between the partitions 2 toward one of the. said partitions and away from the other partition. Consequently that spring 11 which is provided with the stop 12 bearing against thepartition away from which the weight 10 movesis elon ated and at the same time the rods 7, 8 an 9 are moved longitudinally through the partitions 2. The movement of the rod 9 causes the needle or pencil 13 to move transversely of the chart 15 and consequently the said pencil makes marks on the said chart which indicate in pounds the force of the impact or jolt. In view of the fact that the chart is moving longitudinally and the needle moves transversely of the same it is an easy matter to determine sub sequently just exactly where said jolt or jar took place and if the jar was violent and damageresulted to the goods upon the car the crew having charge of thecar may be held responsible. l

' After one of the springs 11 has been elongated as above described and-the' jar ceases the said spring. contracts to its normal length and at the same time the other spring together withits stop 12 will prevent the 35.- "tions and will bring the weight 10- to a prompt stop at its normal position between the partitions 2. This is due to the fact that the inner ends of the springs 11 are fixed to weight 10 from vibrating between the partithe opposite sides of the weight and the .said springs pass through 'the' partitions 2 and are provided at their outer ends with the stops 12 which normally bear against the outer surface of the said "partitions. Therefore it will be seen that an impactregister of simple structure is provided and that the parts mutually cooperate with each'other to accurately determine the force of impact and the blame or responsibility for damage done rolling stock.

Having described the invention what is claimed is 1. ,An impact register comprising a record strip, a supply drum and a receiving drum positively geared together, a plurality of I horizontally movable spring balanced rods, and a weight connecting all of said rods.

2. An impact register comprising a frame, a plurality of horizontally movable spring balanced rods supported in said frame, a

weight connecting all of said rods, and a recording strip acted upon by a pencil carried by one of said rods.

3. An impact register comprising a frame,

a pluralityof horizontally movable spring balanced rods supported in said frame, a

weight connecting all of said rods, stops carried by said rods for limiting their move.-

.ments, anti-friction rollers supporting one of said rods so as to sustain the weight, and

a recording sheet adapted to be acted upon by a pencil carried by one of said rods.

4. An impact register comprising a plurality of horizontally movable spring balanced rods arranged one above the other, a weight connecting all of said rods, antifriction rollers engaging the lowermost rod,

- a pencil carried by one of said. rods and engaging a sheet mounted for movement transversely of said rods.

5. An impact register comprising a frame, a plurality of rods freely mounted in said frame, a weight carried by said rods, springs mounted upon each side of said weight tonormally retain the weight and rods in a WVILLIAM P. SAVAGE.
